Abstract

A color image is recorded on film at the television field rate with alternate film frames representing the luminance and chrominance information. The chrominance information is encoded by filtering the color image through a striped color filter. On playback two line scanners are used to simultaneously scan the luminance and chrominance frames to provide the desired information simultaneously. A decoding signal is used to decode the encoded chrominance information and derive color-difference signals.
